Verification of the LIRA-FEM software / Тест 3.1 Steel wire rope with a specified pitch / Analytical Solution: The Designer's Handbook of Calculation and Theory, ed. by Prof. A.A. Umansky, Moscow: "Construction Publishing House", 1960, pp. 321 - 327.

Geometrically nonlinear problems for threads, cable-stayed trusses, rods, membranes and plates

Analytical Solution:: The Designer's Handbook of Calculation and Theory, ed. by Prof. A.A. Umansky, Moscow: "Construction Publishing House", 1960, pp. 321 - 327.

Geometry:

l = 100 м;
F = 12 см²;
f = 5 м.

Material characteristics: Е = 16 х 10⁶ т/м².

Boundary conditions: Points A and B are fixed.

Stresses: P = 1 т, weight of the rope g = 10 kg/m.

CALCULATION RESULTS:

Point	The desired value	Analytical solution	Calculation results (LIRA)	Uncertainty,%
	Order Н, т	6,45	6,46	0,15
	N_max, т	6,53	6,54	0,15
l/2	ΔZ_max, м	5,81	5,825	0,26
